MULTIPLE FREQUENCY ANTENNA

摘要

Having as an object the ability to stably receive GPS signals, and to be capable of being mounted in an arbitrary location on a car body, a GPS antenna 10 and a matching board 9 are built into a cover 2. An antenna element 1 is connected to the matching board 9. The matching board 9 is arranged in a standing condition, the grounding effect of the GPS antenna is enhanced, and adverse affects are not generated even when a GPS satellite is at a low angle of elevation. Because the antenna element 1 is attached in an inclined condition from a vertical line, adverse affects are not generated even when a GPS satellite is at a low angle of elevation.
